High Strength Low Density Titanium Round Bar Ø4mm x 250mm - China Suppliers & Factory Offer
Product Description
Titanium is the best of all metals and a key material for reducing weight and increasing efficiency in the aerospace industry. Titanium is resistant to extreme corrosion (seawater/acid/alkali), has no rejection reaction in medical implants, and can be used by the human body for life. At the same time, titanium has strong adaptability to extreme environments, can remain stable from deep cold to ultra-high temperature environments, is non-magnetic, has small thermal deformation, and is suitable for precision equipment and electromagnetic sensitive scenarios.
Titanium Round Bar Key Features
Excellent specific strength (strength/density ratio)
Density is only 60% that of steel (approximately 4.5g/cm³). Still, its strength is comparable to that of steel (e.g., TC4 alloy has a tensile strength of ≥ 895MPa), making it an ideal material for aerospace lightweighting.
Excellent corrosion resistance
Dense oxide film (TiO₂) is formed on the surface, which can resist seawater, chlorine ions, acid, and alkali media (especially resistant to chloride corrosion), with a life span far exceeding that of stainless steel.
Biocompatibility
Non-toxic and compatible with human tissues, it is the preferred material for implantation of medical devices (e.g., artificial joints, bone nails).
High temperature stability
Operating temperature up to 400-600°C (e.g., Ti-6Al-4V), suitable for high temperature components such as engines.
Low coefficient of thermal expansion & non-magnetic
Small thermal deformation, suitable for precision instruments; non-magnetic, used in MRI equipment, submarines, and other electromagnetic-sensitive environments.

Applications
Aerospace
Structural components: aircraft landing gear, engine compressor blades, rocket casings (weight reduction to improve fuel efficiency, Boeing 787 titanium usage of 15%).
Fasteners: high-strength bolts, rivets (anti-fatigue, high-temperature resistance, to protect flight safety).
Medical implants
Orthopedics: artificial hip joints, spinal rods, dental implants (close to the modulus of elasticity of bone tissue, reducing “stress shielding”).
Cardiovascular: heart stents, surgical instruments (anticoagulant + non-allergenic).
Marine engineering
Deep-sea equipment: submarine pressure-resistant shells, seawater pipes, valves (seawater corrosion resistance, life expectancy of 30 years or more).
Ship components: propeller shafts, heat exchangers (resistant to marine microbial corrosion).
Chemical & Energy
Corrosion-resistant equipment: reactors, pumps, and valves, electrolyzer (alternative to stainless steel to deal with hydrochloric acid, wet chlorine gas, and other media).
Nuclear power: nuclear waste containers (resistance to radiation + long-term stability).
High-end industry
Racing/Sports equipment: bicycle frames, golf clubs (high rigidity, weight reduction to enhance performance).
3D printing: titanium alloy powder printing of customized parts (medical implants, aerospace complex structures).
Processing and selection recommendations
Commonly used grades
Industrial pure titanium (Gr1-Gr4): corrosion resistance priority (chemical piping).
Ti-6Al-4V (Gr5): high-strength mainstay (aerospace/medical).
Surface treatment
Anodized (enhanced wear resistance), sandblasted (medical roughness to promote bone integration).
Alternatives
Titanium-clad steel (composite construction) or high-nitrogen stainless steel for cost-sensitive scenarios.
Frequently Asked Questions
Q What are the main advantages of using titanium round bars?
Titanium round bars offer an excellent strength-to-weight ratio (density is only 60% of steel), superior corrosion resistance to seawater and acids, outstanding biocompatibility for medical applications, high-temperature stability up to 400-600°C, and non-magnetic properties.
Q Which grades of titanium round bars do you supply?
We supply a wide range of grades including TA1-TA4, TA8-TA10, TA15-TA18, GR1-GR5, GR7, GR9, GR11, GR12, TI-6AL-4V, and TI-6AL-4V Eli1.
Q Why is titanium highly recommended for medical implants?
Titanium is non-toxic, non-allergenic, and highly compatible with human tissues. Its modulus of elasticity is very close to bone tissue, which reduces "stress shielding" and makes it the preferred material for joint replacements and dental implants.
Q What standards do your titanium round bars conform to?
Our products are manufactured in strict accordance with international standards including GB/T2965, GB/T13810, ASTM B348, ASTM F67, AMS4928, and ASTM F136.
Q How does titanium perform in marine and chemical environments?
Titanium forms a dense, protective oxide surface film (TiO₂) that provides exceptional resistance to seawater, chlorine ions, acids, and alkalis, offering a lifespan far exceeding stainless steel in corrosive environments.
